IPC: F15B13/08
Filed: 1963-04-30
Granted: 1964-05-22
Abstract: 980,933. Valves. HYDRAULIC UNIT SPECIALTIES Ltd. June 6, 1962 [May 3, 1962], No. 21974/62. Heading F2V. A number of hydraulic control valves 6, Fig. 1, are sandwiched between top and bottom manifolds 7, 8, the top manifold having supply and exhaust ports 10, 11 although the latter could be disposed in the bottom manifold 8. The control valves 6 are of the open-centre type for parallel operation of double-acting hydraulic motors. Each valve 6, Fig. 2, embodies a bore 16 slidably housing a control spool 17, which bore is intersected by ducts 13, 14 leading to motor ports 15, exhaust ducts 26, 27 leading to an exhaust header 20, and an open-centre supply passage 19, that extends from the supply port 10 to the bottom manifold 8, which leads to the exhaust port 11 via the exhaust header 20; an additional supply header 21 passes through each of the valves from the supply port 10 but dead-ends at the junction of the lower valve and bottom manifold. The supply and exhaust headers 21, 20 are on opposite sides of the passage 19, and a pair of interconnected high-pressure ducts 31, 32 also intersect the bore 16, which ducts direct the supply pressure to one or other of the ducts 13, 14 depending upon the direction of translation of the spool from the neutral position, such movement blocking the passage 19 and constraining the liquid to flow through the header 21, which is connected to the ducts 31, 32 by a branch 35, Fig. 4. The branch 35 of each valve incorporates a check valve 36 held in place by the spring 42 thereof bearing against the adjacent valve or manifold. The abutting faces of adjacent valves or manifolds are provided with seal means 43, 44 as described in Specification 980,932, and the check valves 36 are disposed in the sealed zone whereby any supply pressure leaking past the check valves is directed to the exhaust header 20. Series-parallel operation may be realized by connecting each branch 35 with either branch 28, Fig. 2, of the passage 19. In a modification, four valves 50-53, Fig. 7, are sandwiched together providing for alternate parallel, and series-parallel operation; any other arrangement may be selected. The check valve springs, which are supported in seals 60, may be held in place by spring rings, not shown.

Filed: 1958-01-14
Abstract: Amphoteric ion exchange polymers are derived from monomeric dialkyl or diaryl hydrogen phosphates by reaction of the phosphonates with suitable polymeric materials followed by partial hydrolysis to introduce the amphoteric properties.  The resulting polymers have the structural unit formula:  <FORM:0859834/IV(a)/1> where R is an alkyl or aryl group, R1 and R2 are alkyl or aryl groups or hydrogen atoms or comprise a unit of a polymeric chain, and R3 and R4 are alkyl or aryl groups or hydrogen atoms or comprise a unit of a polymeric chain or together with the nitrogen atom form a piperidine or morpholine group, but are not both hydrogen atoms, at least one of R1, R2, R3 and R4 being a unit of a polymeric hydrocarbon chain.  Examples are given of the preparation of the following polymeric hydrocarbon chains: (1) acetaldehyde-aminomethyl polystyrene, (2) pyridine-2-aldehyde-imino polystyrene, (3) resacetophenone-formaldehyde-ethylamine condensate and (4) diazotised amino polystyrene.  Hydrocarbon chains (1)-(3) are converted into the ion exchange resin by reaction with diethyl hydrogen phosphonate and hydrocarbon chain (4) is converted by reaction with diethyl alpha-ethylamine ortho-hydroxybenzyl phosphonate (see Group IV(b). The amphoteric properties are introduced by treatment with hydrobromic acid followed by aqueous sodium hydroxide.  Specification 855,009 is referred to.ALSO:Diethyl alpha-ethylamino orthohydroxybenzyl phosphonate is prepared by refluxing a mixture of salicylaldehydeethylimine and diethy hydrogen phosphonate in xylene. The product is in the form of colourless crystallinie plates of melting point 305 DEG -306 DEG  C. Specification 855,009 is referred to.

Title: Improvements in or relating to permanent hair waving
IPC: D01C3/00
Filed: 1945-01-17
Abstract: In the treatment of hair by a permanent waving process, the hair fibres are relaxed and rendered more extensible and deformable by the application of a solution of a water-soluble bisulphite, the cation of which contains a monobasic nitrogenous organic base.  Salts of primary, secondary or tertiary amines, or of quaternary ammonium bases may be used.  Bisulphites of methyl, ethyl, propyl, butyl and amyl amines, ethanolamine, aniline, dimethylamine, diethanolamine, trimethylamine, triethanolamine, tetramethyl ammonium hydroxide, morpholine, pyridine, imidazole, guanidine and amino guanidine are specified.  Preferably, a salt of an organic base having a molecular weight below 150 is used. The relaxed hair fibres may be deformed and permanently set in their deformed state by customary methods such as the use of an oxidizing solution or prolonged washing with water.  In an example, hair is soaked in a solution of monoethanolamine bisulphite containing 10 per cent of SO2 and having a pH value of 5.5 at 20-40 DEG  C.  The time of treatment may be 15 minutes at 35 DEG C.  Specification 453,700 is referred to.

Abstract: 739,239. Balls for games. UNITED STATES RUBBER CO. Jan. 18, 1954 [Feb. 26, 1953], No. 1394/54. Class 132(2). [Also in Group V] A play-ball or a practice golf or base ball comprises a spherical core formed of a flexible closed-cell expanded uniform mixture of a vinyl resin, a vulcanized rubbery material and high-boiling organic liquid plasticizer, said rubbery material before vulcanization being compatible with and capable of plasticizing the vinyl resin, and a thin continuous unexpanded plastic shell surrounding the core, the shell being adherent to the core, flexible and highly wearresistant. A mixture of polyvinyl chloride, butadiene-acrylonitrile copolymer, ester type liquid plasticizer, blowing agent, stabilizer, volcanizing agent, antioxidant and pigment is mixed together preferably to a putty like consistency, extruded and cut off into lengths. Each length is placed in a mould filling it to excess and the excess is removed. The soproduced quantity is then placed in a mould 2, 3 of slightly greater volume and heated under pressure to expand and cure in part the core, the mould being then cooled and opened. The core is then allowed to expand freely and to vulcanize on an open tray 5 in a current of hot air and is then cooled so that it .contracts. It is then dipped in a shell-forming paint comprising a solvent, polyvinyl chloride, ester-type liquid plasticizer, stabilizer and titanium dioxide and dried. The coated cores are then cooled, e.g. by refrigeration to reduce their diameter to less than the final diameter required and are heated under pressure in a dimpled mould 8, 9 of the required final size. This mould is then cooled and opened. The polyvinyl chloride for the core may contain some vinyl acetate, methyl acrylate, diethyl maleate, or vinylidene chloride. Examples of suitable blowing agents and plasticizers for the core are described. The shell may contain instead of polyvinyl chloride, polymethyl acrylate, polyethyl acrylate, polymethyl methacrylate, polyethyl methacrylate or copolymers of alkyl acrylates and alkyl methacrylates. Detailed description of the process temperatures and mixture proportions is given.
